Manhattan DA candidate Dan Quart endorsed by fellow state lawmaker John Liu Chelsia Rose Marcius State Sen. John Liu (D-Queens) has endorsed state Assemblyman Dan Quart (D-Manhattan), his fellow lawmaker and longtime political ally, in his quest to be the next Manhattan District Attorney. “For years, I have worked in partnership with Assemblymember Dan Quart on issues of fairness and equity for working people in New York City,” Liu said in a statement to the Daily News on Thursday. The state senator also commended his legislative colleague for taking a stance against Manhattan District Attorney Cy Vance, who declined to prosecute several major American banks after the 2008 financial crisis and instead went after Abacus Federal Savings Bank — a Chinatown institution that historically provided financial services to immigrants and other Lower Manhattan residents.
